IMPROVEMENT IN mas FOR CUTTING our ORNAMENTAL FORMS OF PAPER.'

Specification forming part of Letters Patent No. 13?,063, dated March25, 1873.

To all whom it may concern:

Be it known that I, ADOLPH DELKESGAMP, of Brooklyn, E. D., in Kingscounty, New York, have invented a certain Improvement in Dies for Outting out Ornamental Forms of Paper, of which the following is aspecification:

The invention is intended more particularly for the production ofvariously-curved and elaborate slender forms in paper, to be ccmentedupon glass globes and other objects of glass for exposure to thesand-blast. Paper is not cut by the sand, and protects the surfacebeneath it in its polished condition, while the surfaces not protectedare rapidly abraded under the violent impact of the small grittyparticles. The paper forms thus produced may obviously be useful forvarious other decorative and other purposes; and the present inventionmay be applied to the manufacture of forms in other material than paper.

I will proceed to describe what I consider the best means of carryingout the invention, as applied to the production of paper shapes forglass decorating. v

The accompanying drawing forms a part of this specification.

Figure 1 is a vertical section through the upper part of the bed and thelower part of the platen or plunger. Fig. 2 is a vertical section atright angles to Fig. 1. Fig. 3 is a top "iew of the bed with itsattached male die; and Fig. 4 is a view from below, showing the underface of the plunger with its female die.

Similar letters of reference indicate corresponding parts in all thefigures.

I can employ a press of any suitable construction, and operated byhydraulic force or by other means. I do not consider it necessary torepresent the press, but only the novel of an inch, and thus initiatesthe formation of a female die, to be afterward completed, as set forthbelow. hardened steel or other suitable material, firm- 1y secured uponthe upper face of a substantial bed-casting, b. The plunger a. is workedup and down through a considerable space say, an inch or more. The pressshould provide means for depressing it and its attachments with force,particularly at the lower extremity of its motion.

So far as thus described, the parts would cut out the formssuccessfully, but the thin and branching strips of paper thus cut outwould be liable to stick either to the male or female die, or to both. 7

The nature of the work forbids the introduction of any ordinarymeans forclearing the parts. The male die must present a prac tically plane faceto avoid distorting the delicate shapes thus produced. The.wastematerial cut out from the spaces in the pattern ten ding to remainaround and within the spaces in the male die B, need not be so carefullytreated; but I will describe the means which I have adopted, whereby thepaper is freed from both, without distortion. I drill small holesthickly over the entire sunk portion of the female die A A producing theholes quite through the soft metal A, and also through thesupporting-material a above it, and introduce corresponding slender pinsin, screwed or otherwise secured in a plate, D, mounted above, andcapable, not only of moving with the plunger, but also a quarter of aninch, more or less, motion up and down in a recess within the plunger. Icorrespondingly drill holes in the spaces around the male die B, andprovide corresponding pins m correspondingly fixed in a slightly movableplate, M, below. The press operatesthe plate M and its attached pins onby cams and connections not represented, so that at each separation ofthe diesA and B, the pins m are protruded from their respective holesand actively push out the paper lying in their way. I

A gentle current of air from a fan or analogous apparatus may be broughtto bear on the paper as soon as liberated by the pins, so as to moreeffectually remove the waste material; but in many cases such anaddition may not be necessary.

The act-in g ends of the pins m should be B is the male die, formed ofC. H. FANCHER. Farming and Gaging Butter Rolls.
